    Sounds like you have a well worn bike, you need to do some testing, leak down, like previous poster mentioned. It's got lots of blowby that's overwhelming the breather and pushing it out to the carbs. Top end rebuild time. Fix the push rod seals then, as well as anything else. Have Fun.

    im sorry...but what do u mean by 'lots of blowby'? Not sure what this means...appreciate your clarification. And yeah,...it should be a pretty worn bike by the looks of it. I am taking my time to build it up again and is looking at various options,.. Thanks anyway for your comments.

    It might be a good time to do the rubber intake sleeves too.

    It's not hard, you just need to be careful. If you can adjust your own valves, you can do this too.

    This would be oil blowing by the worn piston rings or valve guides...

    Well, cleaned up the air filter and airbox and the oil stopped lieaking for over a week. But it seems to be coming back again...i have noticed a little oil at the bottom of the carb..not enough to drip on me right now..but will monitor it. Push rod seals is worn but in tis case i am convinced it is not the cause. Dunno whether if replacing the breather tube will help?
